For PDFs this function indicates the number of pages on the PDF, NOT images that might be embedded within the PDF.

<?php

$document = new Imagick('2_pager.pdf');

var_dump($document->getNumberImages()); //returns 2

$document = new Imagick('1_pager.pdf');

var_dump($document->getNumberImages()); //returns 1

?>

From my research it is not possible to obtain the images embedded within a PDF by using the PHP Imagick library.

<?php
/* Create the object */
$image = new Imagick('YourImageLocation.tif');
$count = $image->getNumberImages();

echo "<h3 style=\"font: bold 12pt Arial\">Total Number of Images Extracted ".
     "from the TIF : ".$image->getNumberImages()."</h3>";

for ($x = 1;$x <= $image->getNumberImages(); $x++) {
  $image->previousImage();
  $image->thumbnailImage( 400, null );
  $image->writeImage('img'.$count.'.png');
  $count--;
}
?>
